There are still multiple young children missing, including Charlotte Campbell’s 15-year-old daughter, Olivia, who has not been found.

"She was at the concert. She’d just seen the support act and said she was having an amazing time, and thanking me for letting her go. She was with her friend, Adam. Adam was found about half an hour ago – he’s in hospital – but Olivia’s not been found yet," she told BBC Radio 4.

"I’m at home phoning everybody: hospitals, police, the centres that the children have been put in. Her dad’s actually in Manchester looking for her. I’ve got friends looking for her. I’ve got people I don’t even know looking for her, people messaging me, saying we’ve got her photo, looking for her, we’ll get in contact if we see her. And I’m just hearing nothing. Her phone’s dead.

"They’ve basically told me to stay put and wait for a phone call. I daren’t leave the house just in case she somehow gets home."
